What are opposing curves?

Question

I have been reading a book about figure drawing and it states that opposing curves are an important concept for drawing figures and other forms in nature. Could anyone explain in a simple way what the opposing curves concept is about?

Answer 1

Opposing curves create balance in a image. Think about the letter S. It curves one way and - before it can become a circle - curves the other way. Without the second curve, it would look uneven - like it should just roll over. By alternating the curve, you create a pleasing and natural looking image. Look for it in nature: curves in the body, flowers, etc.
